> In the class ForkUtil, mask values have been computed and stored in static 
> final vailables, but they are recomputed for every encoding, which may be 
> unnecessary. 
> anther small fix is that change
> {code:java}
> remainingBitsPerValue > remainingBitsPerLong{code}
>  to
> {code:java}
> remainingBitsPerValue >= remainingBitsPerLong{code}
> otherwise
> {code:java}
> if (remainingBitsPerValue == 0) {
>  idx++;
>  remainingBitsPerValue = bitsPerValue; 
> }
> {code}
> these code will never be used.
